Home / Custom / Optical Components / Optical Spherical Lens / Plano Convex L Lens 
Plano-convex L lenses/Mirrors are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. The use of a plano-convex L lens/mirror is ideal for all-purpose focusing elements.If you want to know more information about a plano-convex lens/mirror, such as the use and refractive index of a plano-convex lens, please contact us.
Optical glass such as K9, fused silica, sapphire, MgF2, silicon (Si), ZnSe, ZnS, etc. These materials possess high transmittance, low absorption, low scattering, uniform refractive index, and specific dispersion characteristics.
Precisely hemispherical. The machining precision of the center and radius of curvature of the sphere is extremely high.
The surface is precision polished to an optical grade of 10-5 to ensure image quality and reduce scattering and aberrations.
An AR coating is typically applied to the concave surface to maximize the transmittance of specific wavelengths of light (e.g. visible light) and reduce reflection loss.
